Abstract

A fully collapsible headset assembly includes a headband portion formed by side arm members articulated together by a flexible hinge member. The flexible hinge member includes an elastic cam member, the force of which is released to maintain the assembly in either an operating or collapsed position, as desired. In the collapsed position, the tension of the cam member maintains a permanent pressure and the headband assembly forms a cavity in which the facing ear-cups are retained.

Claims

1. A headset assembly which is adapted to engage a user'"'"'s head and ears to provide noise protection, cold protection or listening to sound signals;

including in combination;

ear-cup members for engagement with user'"'"'s ears;

a headband portion comprised of a pair of side arm members, each side arm member having a proximal end and a distal end, with said side arm members coupled together at their proximal end by a first hinge assembly, with each of said distal ends having a second hinge assembly coupled to a support member, with said support member structurally arranged to receive and mount said ear-cup members;

wherein said ear-cup members are operatively connected to said support member by a third hinge assembly; and

whereby said first hinge assembly permits said side arm members to articulate between a collapsed position and an operating position, with said first hinge assembly including a cam member which selectively biases said headband portion into and in said collapsed position.

2. The headset assembly in accordance with claim 1, wherein said first hinge assembly includes a ledge and recessed type of hinge coupling between said proximal ends of said side arm members to provide a biasing cam action to retain said headband portion in said collapsed position.

3. The headset assembly in accordance with claim 2, wherein said first hinge assembly further includes a hinge pin in said proximal ends of said side arm members for pivotally hinging said ledge and recessed type of hinge coupling together.

4. The headset assembly in accordance with claim 1, wherein said first hinge assembly is comprised of an elastic cam member formed by at least a hinge pin and at least a ledge formed at the proximal ends of said side arm members, with said ledge contacting in a forced way a recess at the proximal end of the opposing side arm member.

5. The headset assembly in accordance with claim 1, wherein said first hinge assembly includes an elastic cam member positioned at the proximal ends of said side arm members and ledges which are structurally arranged to be received by recesses located at the end of the opposing side arm member.

6. The headset assembly in accordance with claim 1, wherein said headband portion is comprised of a plastic material.

7. The headset assembly in accordance with claim 1, wherein said side arm members are curved so that they complement each other to form a folding cavity structurally arranged to enclose both ear-cups therein when in said collapsed position.

8. The headset assembly in accordance with claim 1, wherein said ear-cup members include padded frames which are elastically compressible when in said collapsed position.

9. The headset assembly in accordance with claim 1, wherein said support members of said second hinge assembly are U-Shaped forked members which are operatively connected to respective ear-cups by said third hinge assembly.

10. The headset assembly in accordance with claim 9, wherein each of said U-shaped forked members have leg portions which define a channel therein which is structurally arranged to cooperate with said third hinge assembly to provide maximum folding when in said collapsed position.

11. The headset assembly in accordance with claim 1, wherein said second hinge assembly includes a cam member comprised of ledges formed in the articulated contact area between said support members and said distal ends of said side arm members.

12. The headset assembly in accordance with claim 1, wherein said third hinge assembly is positioned between said ear-cup members and said support members of said second hinge assembly.
